Colloids are valuable model systems to understand the structure and dynamics of matter, explore new self-assembly concepts, and realize advanced materials. Herein, we demonstrate social self-sorting of co-assembled families of colloids by orthogonal host/guest recognition using cyclodextrins. We show that mixtures of four partners self-sort into their respective families without mutual interference. Additionally, the self-assemblies and their interactions are switchable using orthogonal triggers. This study goes beyond previous features of molecular self-sorting, and opens the design space for future self-sorting colloidal systems via rationally designed molecular recognition.
胶体是理解物质结构和动力学、探索新的自组装概念和实现先进材料的有价值的模型系统。在此，我们通过使用环糊精的主客体正交识别，展示了胶体共组装体的社会自分类。我们表明，四种配体混合物可以在没有相互干扰的情况下自分类到各自的家族中。此外，自组装及其相互作用可以使用正交触发进行切换。这项研究超越了分子自分类的先前特征，并通过合理设计的分子识别为未来的自分类胶体系统开辟了设计空间。
